ACETYLENE-GAS MACHINE.

SPECIFICATION forming part of Letters Patent No. 660,889, dated October 30, 1900.

` Application tiled April 19, 1900. Serial No. 13,492V (No model.)

T0 all whom, t may concern: y

Be it known that I, JOSEPH M. CoeHLAN, a citizen of the United States, and a resident of Sayville, in the county of Suffolk and State of New York, have invented a new and Improved Gas-Machine, of which the following is a full, clear, and exact description.

This in vent-ion relates to improvements in gas-machines for generating gas from calci um carbid; and the object is' to provide a gasmachine of simple construction in which there will be an economy in lthe use of carbid and a novel means for automatically immersing the carbid.

I will describe a gas-machine embodying my invention and then point out the novelY features inthe appended claims.

Reference is to be had to the accompanying drawings, forminga part ofthis specification, in which similar characters of reference indi-v cate corresponding parts in both views.

Figure 1 is a sectional elevation of a gasmachine embodying my invention, and Fig. 2 is a sectional elevation of a purifier employed.

The gasometer comprises the usual fixed section 1 and the bell 2. The fixed section4 near its top has a funnel-shaped opening 3, through which water may be poured to sup ply the gasometer. Arranged adjacent to the gasometer is a generator', comprising a cylin-4 der 4, open at its lower end and having a removable cover-which is held tightly in placev by means of a screw 6, passing through a yoke 7, attached to an arm 8. Removably sup` ported in the cylinder 4 is a basket-like framev 9, in which the open-Work carbid-holders 10 are placed. I have here shown three of these carbid-holders arranged one above another;

but obviously a greater or less number may be employed. Portions of the upper end of 'the frame 9 areturned outward to engage upon supporting-lugs or the like on the inner side of the cylinder 4. Water is supplied to the carbid, and the supply is controlled by movements of the gasotneter-bell. As here shown, the water is placed in a vessel 11, into which the lower portion of the cylinder 4 ex-` tends. This vessel 11 is movable up and down relatively to the fixed cylinder 4, and I have here shown it as provided with a bail12, from which a rope or similar device 13 exto receive the connections 13 and 16.

levers are pivoted to `a rod 17, extended up- 6o 'mentally-shaped lever 15, from which a con- 55 nection 16 extends to the bell 2, as plainly indicated in Fig. 1. The periphery of the? segmental levers may be curved or channeled These ward at one side of the gasometer andconnected tothe fixed .portion thereof.

From the upper portion of the generating-/\ cylinder 4 a supply-pipe 18 extends downward and communicates with the lower portion of a purifier-cylinder 19, arranged atone side of the gasolneter, and from the upper portion of this purifying-'cylinder 19 a pipe 20 Vleads into the gasometer and has its upper end turned downward, terminating below 7o the level of the water in the gasometer. Removably placed in the cylinder 19 is a basket 2l for containinga purifying material for the gas, and in the lower portion of this cylinder,

below the basket 21, asmall amountof water 22 is placed. A Water-seal pipe 23 communicates with the bottom of said cylinder 19. A service-pipe 24 extends into the gasometer to a point above the water-leveland then outward through the fixed portion to the burners. 8o

To prevent accident from overpressure of gas, I provide a blow-ott device having connection both with the service-pipe and with the supply-pipe 18, leading from the generator. and may be located at any desired place, from which cylinder a pipe 26 leads to some point out of doors. A small tube 27 leads from the service-pipe 24 and terminates in a double turn or gooseneck 28, which has its open end 9o below the surface of water contained in the cylinder 25. From the pipe 18 at a point above its valve a tube 29 extends into said cylinder 25 and has a double turn or gooseneck 29a, having its open end below the level 95 of the water in the cylinder 25. Water may be placed in the cylinder 25 through a funnel 30.

In operation, when the gas is generated from the material contained in the lowermost Ioo holder 10 the bell 2 will be moved upward. V Then as the supply of gas contained in said vessel is reduced the said bell will move downward, rocking the compound levers 14 and 15 This blow-ottl consists of a cylinder 25 85.

and drawing the vessel 1l upward to immerse the second holder for carbid, and this of course will be continued 'until all of the carbid is destroyed for gas-making purposes. The gas generated will pass through the pipe 18, and thence through the purifier and the pipe 2O to the interior of the gasometer. Should an overpressure occu r in the pipe 24, an escape will be found through the tube 27. This escaping gas will pass into the water contained in the cylinder 25, and thence up through the same and out through the pipe 26. Should an overpressure occur in the generator, this gas will pass up through the tube 29 and out, as before described, through the pipe 26.

Having lLhus described my invention, I claim as new and desire to secure by Letters Patentl. In a gas-machine, a gasometer, compriswing a bell, a generator, consisting of a fixed cylinder adapted to hold calcium carbid, a

vessel for containing water into which said cylinder extends, and connections between said vessel and the gasoineter-bell, whereby the vessel is raised or lowered by movements of said bell, substantially as specified.

2. A gas-machine, comprising a gasometer, a generator-cylinder arranged adjacent thereto, a water vessel into which the generatorcylinder passes, a segmental lever having connection with said vessel, and another larger segmental lever connected to the first-named segmental lever and havinga connection with the gasometer-bell, whereby the water vessel is raised by the lowering of the bell, substantially as specified.

3. In a gas-machine, a gasometer, a generator arranged at one side thereof and having pipe communication with the interior of the gasometer, a service-pipe leading from The gasometer, a blow-off cylinder for containing water,a tubeleading from the first-named pipe and having its end turned downward and then upward within the blow-off cylinder, and a tube leading from the service-pipe and having its end turned downward and then upward within said cylinder, substantially as specified.

ln testimony whereof I have signed my name to this speci'ication in the presence of two subscribing witnesses.

JOSEPH M. COGHLAN.
